Rancho RS9000XL 2.5″ Rear Lift Shocks for 1999-2004 Ford F-350 4WD

Part Number: RS999254

Summary: The Rancho RS9000XL series provides the ultimate in ride control for the Ford F-350, featuring a globally recognized 9-position manual adjustment knob. This Tier 2 adjustable system allows drivers to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road stability. Engineered to accommodate 2.5 inches of rear lift, these shocks solve the problem of “one size fits all” valving by putting damping control directly in the user’s hands.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the vehicle is perfectly dialed in for street, trail, or towing applications.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure consistent cooling and reduced fade during heavy-duty hauling.
• Nitrogen Gas Charged: High-pressure gas optimization provides a faster response rate to ensure tire-to-road contact is maintained over washboard terrain.
• Protective Boot: A heavy-duty poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity in harsh environments.
